The Bermuda solar rope light is a string of 36 LED lights. Ideal for adding a touch of style to your pond or garden trees or shrubs. The lights can be floated on the surface of your pond or even weighted down at the bottom. These are a real multi functional decretive feature. As the lights are solar powered, the solar panel will automatically charge the battery throughout the day, then automatically turn the lights on at night. Once fully charged, you can expect up to 4 hours of light.
